From 158,366 reviews, clients rate our Flutter Engineers 4.9 out of 5 stars.Hii I'm student in 20 years old i don't have any technical skills so i have a app idea for self improvement daily tasks I'm now just exploring i have mapped out a mobile application that helps young, phone-addicted users replace mindless scrolling with daily, purposeful challenges. The core idea is simple: each morning the app delivers a mix of physical activities, social tasks, and other productive lifestyle actions. When a user completes a task, the app confirms it automatically by monitoring their phone-usage patterns— Here is the vision I need you to turn into code: • A clean, cross-platform app (iOS and Android) that releases one new challenge per day and tracks streaks, points, and leaderboards. • Automated task validation that relies on app-usage ...

I need a complete mobile application that lets my team handle our warehouse inventory from the shop floor without ever touching a desktop. The core of the project is solid inventory management: every item should update in real time the moment it is received, moved, picked, or shipped. Key features I must see working smoothly: • Real-time tracking so quantities stay accurate down to the last unit. • Automatic stock-level alerts that notify staff before we run low or hit overstock. • Fast barcode scanning using the device camera (or external scanner) to add, find, and reconcile items instantly. The app has to feel quick and intuitive on both Android and iOS, with a lightweight back-end that keeps data synchronized across multiple devices. I’m open on the tech...
The goal is to deliver a polished mobile application that serves as the central order-tracking portal for our logistics hub. It must run smoothly on both iOS and Android, giving customers a single place to follow every shipment from dispatch to delivery. Core workflow • A user enters or scans an order number. • The app pulls real-time location data from our existing logistics system and displays it on an interactive map. • At each status change—picked up, in transit, out for delivery, delivered—push notifications fire instantly. • All completed jobs are stored locally in a searchable order history that can be viewed online or offline. Technical expectations • Cross-platform codebase using Flutter or React Native is welcome, but separate nati...
I want to replace the simple YouTube links inside our current UTKALA Sikhya Niketan apps with a fully embedded, native live-classroom. Your task is to wire the Flutter front-end to an SDK such as Agora or 100ms (I’m open to your recommendation) and switch the existing classes to that real-time experience, complete with in-session chat. Students will enter sessions through a one-time-password login flow; no social or email / password combinations. In parallel, I need a brand-new career-counseling section on the web portal. The public side should let students browse available mentors, pick a time slot, and confirm the booking. Behind the scenes the counselors need their own workspace with: • Appointment management • Session notes • Progress tracking A basic &ldq...
I’m kicking off a new mobile-first social networking platform and need the initial version of the app built around a rock-solid user-profile system. The first milestone is simple but crucial: users must be able to register, upload an avatar, edit their bio and basic details, and browse other members’ profiles in an intuitive interface. You’re free to choose the tech stack you’re most productive with—whether that’s Flutter, React Native, Swift / Kotlin, or another modern framework—as long as the result runs smoothly on both iOS and Android and can scale once we add messaging and a news feed later on. Clean, well-commented code and Git version control are a must so future features slot in easily. Deliverable • A fully functional mobile a...
I need a cross-platform e-commerce application built from the ground up so customers can browse, purchase, and track products seamlessly on both iOS and Android. React Native or Flutter are both fine; stability, speed, and a polished native feel are what matter most. Core scope The build should cover everything from the shopper-facing interface to the lightweight admin tools I’ll use to upload items, view orders, and push promotions. A clean product catalogue, smooth cart flow, and secure checkout are mandatory, plus basic analytics so I can monitor sales and user behaviour. Design & brand assets A simple, modern UI is preferred—think clear product images, intuitive navigation, and quick access to support. I already have a colour palette and logo that can be shared on...
Project: School Bus Tracking & Child Journey Tracking – MVP/POC I am looking for a developer to build a very small functional POC for a school transportation tracking system. This is not the full production application. The POC will be tested on 1 school bus with approximately 20–30 students. Required features: 1.

I'm seeking an experienced mobile app developer from Switzerland to finalize and optimize my cross-platform social networking app. The app is written in JavaScript and already live on Apple but requires adjustments before re-uploading with a corrected description. Tasks include connecting the invite link to the download option, enabling users to report inappropriate pictures, guiding me on managing images via Superbase, fixing typos, adjusting pop-ups, ensuring email collection functionality, and launching on Google Play. Additionally, I need professional guidance for SEO optimization and promotion post-launch.
I’m building a simple yet secure solution that lets visitors enter and leave our gated community by scanning a QR code. The core flow is straightforward: • Residents create a unique, time-bound QR code for each guest from within the same app (or their own resident view). • The visitor presents that code at the gate, security scans it, and the visit is automatically logged as “checked-in.” • On departure the guard scans again, closing the visit record as “checked-out.” That check-in / check-out cycle is the only must-have for this first version. I do not need broader resident-notification features or an elaborate security dashboard right now—speed and reliability of the QR workflow are my priorities. Deliverables I expect: 1. Cross-p...
I am building a complete smart-mailbox platform and need you to take care of every software layer. The web side must be developed in Laravel (latest stable/LTS) and will handle user registration, secure login, mailbox pairing, a live dashboard that shows whether the lid is open or closed, and a simple settings area where each user can enable or disable mobile push alerts. A companion app written in Flutter will run on both Android and iOS. After signing in, the user should instantly see the current mailbox status, browse a short history of recent events (the system only keeps records for a configurable, limited period), and receive push notifications whenever the Tuya smart switch detects a new “open” event. The delivery person from the postal company will be able to read a...

I am looking for an experienced developer or development team to build an on-demand home-services marketplace for the Kenyan market. The concept is similar to Uber, but instead of transporting passengers, customers will request verified artisans/fundis for home and business services such as plumbing, electrical work, carpentry, painting, welding, appliance repair and other services. ### Required platforms 1. Customer mobile application 2. Artisan/Fundi mobile application 3. Web-based admin dashboard 4. Backend/API ### Core customer features • Phone/OTP registration • Location/GPS (critical priority) • Real-time chat functionality (critical priority) • Service categories • Nearby fundis • Immediate or scheduled bookings • Job posting with ...
I already have the master logo files and they must remain pixel-perfect everywhere—Splash screen, 1024×1024 App Store icon, 512×512 Google Play icon, app home, website landing page, and every new screen we add. No colour tweaks, no sizing changes, no layer edits; please drop the artwork in as-is. Inside each of the four gold buttons (About Us, Add Businesses, Contact Us, Language), the search bar, and every category square, add a small white diamond in the top-right corner. It should match the proportions of the diamonds that already appear in the interface so the visual rhythm stays consistent. The fifteen category squares you will wire up are: • Accommodation • Food • Industry • Commerce • Nature • Nightlife • Gas Statio...
I’m planning a new social media application and need a developer who can take it from concept to launch on both iOS and Android. The heart of the product is a dynamic News feed where users will scroll through posts from the accounts they follow. Each post should support rich text, images, or short videos and refresh in real time. Key interactions I want implemented from day one are Likes and comments plus the option for users to Share posts directly to their own feed. Smooth, snappy performance and modern gesture-based UI patterns are important to me, and I’d like push notifications in place for activity on a user’s content. I already have initial wireframe sketches and branding assets, so you’ll focus on the full mobile build, backend APIs, and deployment to the ...
I am building an end-to-end AI platform: The build must cover: • iOS • Android • Web The work involves taking an excellent base model (such as Meta’s Llama or Mistral AI) and adapting it to your niche using techniques like fine-tuning or RAG (Retrieval-Augmented Generation). Adding data must also be made possible through a simple and intuitive interface. The platform must allow users to write questions and read answers, but also feature a graphical interface that enables the exchange of opinions and realistic debate with the user. What I expect from you is a fully functional, production-ready system—front-end, back-end, and model integration—delivered with clear documentation and deployment assistance so my team can scale it after launch. If you al...
I want a lightweight Android app that can read the live feed of 1xBet’s Crash game and forecast the crash point a few seconds before each round stops. Mobile is the only environment I need covered, so everything you build should install cleanly on recent Android versions without side-loading gymnastics. The core of the project is the prediction engine. Whether you choose pure probability modelling, machine-learning, or a hybrid approach, the algorithm must process real-time data from the game screen or API and return a single number—the expected multiplier at which the round will bust. A simple, distraction-free interface that shows the current round, your predicted crash point, a confidence score, and a quick history log is enough for version one; fancy charts can wait. You&...
I’m assembling a cross-platform solution that links university students to corporate recruiters through three core experiences: • Student profiles that hold rich, searchable content—at launch this means text descriptions and images, with embedded project links and dynamic skill tags. • A job board where students slice results by role type, location, domain and salary. • A Kanban-style ATS for recruiters, mirrored by a real-time status dashboard on the student side. Authentication is social-only for now, using Google OAuth. Please structure the auth layer so additional providers or SSO can drop in later without a refactor. Tech stack expectations Web: React.js or Next.js. Mobile: Flutter or React Native—feature parity with the web version. Backe...
I run a small clinic and need a straightforward mobile application that lets my team capture, store and pull up a patient’s complete medical history at any moment. The heart of the build is a structured medical-history module linked to a prescription writer, so a doctor can open a chart, review past notes, add today’s findings, then generate and save a new prescription—all from one screen. The app has to work smoothly on modern smartphones, store data securely on-device first, and give me an easy way to back up or export records (PDF for individual visits and CSV/JSON for bulk data). A quick search by name, phone number or patient ID is critical because we often look up a file while the patient is sitting in front of us. Appointment scheduling is not a must-have right no...
Sefadinbadhasoo is the working title for a brand-new initiative I want to bring from rough concept to concrete reality. At this stage the idea is still fluid, so the first task is a structured discovery sprint that defines the project’s purpose, ideal audience, and the most effective medium—be it a responsive website, a lightweight mobile app, or a distinctive visual identity. During our initial collaboration you will: • Deliver a concise discovery report that captures objectives, audience insights, and recommended direction. • Propose a phased roadmap with realistic timelines, core milestones, and the tools or stacks best suited to each step (React, Flutter, Figma, or any alternatives you deem fit). • Provide an early-stage wireframe or mood board to conve...
I am looking for an app developer to build a simple android and ios app for residents of a real estate project (very similar to mygate) , i already have created a web application as a reference and want to replicate the exact screens onto the actual mobile app as phase 1 of our project and roll out the app onto app and play store. The first phase would focus on: 1. Replicating the existing web application’s UI/UX and navigation flow on Android and iOS. 2. Connecting the already-existing functional elements where required, such as phone OTP login, database writes, enquiry-to-e-mail flow, and push notifications. 3. Preparing and publishing the mobile applications on both the Google Play Store and Apple App Store. 4. The business data currently shown is demo/static data, with live pa-...
I want to launch a task-marketplace similar to Airtasker that ships on iOS and Android at the same time, so a single cross-platform code-base is essential. Users must be able to create an account instantly with Apple, Google or Facebook, post a job, receive bids, choose a worker, pay safely, and leave feedback once the work is done. For the first milestone I need a fully functional MVP that covers: • Task posting with budget, deadline, photos and real-time bidding/chat • User profiles, verification badges, star-rating and review history • Secure payment integration with hold-and-release logic (Stripe, PayPal or your proven solution) • Social sign-in/out plus email option • Push notifications for bids, acceptances and task status React Native, Flutter or ...
I’m creating a self-guided, two-hour tour that visitors can enjoy even when they have no signal, so every asset—audio tracks, video clips, map tiles, and imagery—must be packaged inside the app bundle and run 100 % offline once the first download completes. Core experience • As soon as the phone’s GPS detects that a traveler has reached a designated point, the matching chapter should start automatically. • Users can still tap Play or Pause at any time, scrub the timeline, or replay earlier chapters if they wish. • An interactive map (shown with the device’s live position) remains available offline and lets users jump to any stop visually. • Short quizzes or checkpoint questions pop up at selected locations to keep people engaged an...
I need a pair of polished mobile apps—one for iOS, one for Android—that lets a traveler open the phone, find a human agent, and finish a booking in a few taps. The entire flow should feel like messaging a knowledgeable friend: the user starts a chat, describes the trip, then reviews flight and hotel options surfaced through live API feeds before paying securely inside the app. Core experience • Dual-platform build (iOS + Android) delivered either natively or with a single codebase such as Flutter or React Native—whichever you recommend for long-term stability and speed. • Real-time messaging between traveler and assigned agent, complete with push notifications and image/file share. • Integrated flight and hotel search tied to a major GDS/OTA API so a...
Subject: Senior Full-Stack Mobile Engineer for Luxury Multi-Language Ride-Hailing Platform (Flutter / React Native) Hi Developers I’m launching a high-end private ride-hailing service tailored for a specific regional market, and I’m looking for an elite mobile developer to bring it to life. I’m not interested in a messy prototype or a generic, clunky template. The vision is to build something that feels genuinely world-class—fluid, visually stunning, and as effortless to use as Uber, but with a sharper, more refined aesthetic. The interface needs to be clean, intuitive for everyday users, and completely frictionless from the moment someone opens the app to when they complete a ride. What We Are Building: The Passenger Experience: A gorgeous, minimalist UI with a ...
I run a building–material wholesale operation and need a cross-platform mobile app (native or well-built hybrid) that lets me keep every stakeholder, from retailers to on-site masons, fully informed and motivated. Retailer module • Retailers log in to record each sale of my products. • The system automatically tallies their sales history and shows real-time overdue balances so both sides always see the same numbers. • I can adjust or upload credit notes, payments received, and comments from an easy web or admin panel, with instant sync to their phones. Mason / builder loyalty module • Every time a mason lifts material from a linked retailer, the retailer records the quantity; the app assigns reward points based on my rules (I should be able to edit multi...
I’m developing a mobile-first social networking platform that will run on both iOS and Android. Core features include profile creation, follower/friend connections, a real-time feed with likes and comments, private messaging, push notifications, and media upload for photos and short videos. A clean, modern UI/UX and smooth onboarding (email, phone, or existing social sign-ins) are priorities, and the codebase should be structured for easy scaling and future feature releases. Cross-platform frameworks such as Flutter or React Native are perfectly acceptable as long as performance matches native expectations; if you prefer fully native builds, outline the benefits you can bring. A lightweight backend/API and basic admin dashboard are also part of the scope, though I’m open to re...
I am looking for a UI/UX designer for ongoing part time work on a mobile app that is already live on Android and iOS. It has real users, so this is design for a product in use, not a concept from scratch. You would design in Figma and hand off to our in-house Flutter developers. You are not writing code, but you will be coordinating closely with them, so designs need to be clear enough that handoff is smooth and questions are rare. This is a long term engagement. I want someone who stays with the product for months and gets to know it, not one quick project. Schedule: this role runs in the evening. I need availability roughly 7 pm to 11 or 12 pm, IST, most working days. Total commitment is 10 to 15 hours a week. What we are looking for: 1. Mandatory: • Strong, conversational Eng...
I need an app that mirrors Biyajkhata’s customer-management flow while running natively on both iOS and Android. The reference app already covers the core screens and logic, so your main focus will be recreating that experience and adding two important extras: • Key numbers panel – a quick snapshot of each customer’s outstanding balance, paid amount, and upcoming due date. • Universal name search – a fast search bar that lets users find any customer from any screen in real time. A cross-platform framework such as Flutter or React Native is fine, provided the final builds are smooth on modern and older devices alike. I’ll share Figma wireframes at project start; you’ll handle coding, basic UI styling consistent with Biyajkhata, and produce p...
I need a fully working mobile application that converts plain-language prompts into accurate SQL statements and is ready to ship on both iOS and Android. The user flow is simple: type or paste a question such as “show me all orders placed this week,” tap a button, and instantly receive a correctly formatted SQL query. From there the query should be easy to copy, share, or save. Cross-platform consistency is essential, so the build must target iOS and Android from the same codebase. React Native or Flutter are both fine; feel free to suggest an alternative if it still produces App Store- and Google Play-compliant release builds. Core requirements • Clean text input with real-time or on-tap SQL generation • Support for at least the major SQL dialects (MySQL, Postgre...
I am building a mobile-first e-commerce application whose initial release focuses purely on a browsable product catalog. This is a mobile app project, not a responsive website, and the core objective right now is to give users an attractive, fast, and searchable catalog experience. What I need from you is an MVP that runs smoothly on both iOS and Android (React Native or Flutter are both fine). Because it is strictly catalog-only at this stage, there is no shopping-cart flow or payment gateway to wire up, but please lay the architecture out so those elements can be added later without a full rewrite. Key areas I will review: • Clean, modern UI that matches standard e-commerce patterns • Efficient data handling for categories, variants, and images • Simple admin o...
Engineer (Flutter + Laravel API) SENIOR FULL-STACK ENGINEER (FULTTER + LARAVEL API — Panda Ride Location: Remote Type: Full-time / long-term contract Reports to: Technical Management About Panda Ride Panda Ride is a ride-hailing platform built to compete directly with Uber, Bolt and Lyft. The platform is already live: a rider app, a driver app, an admin/dispatch panel, a public website and a realtime backend running in production. The foundation is in place — Firebase has been removed from the core, realtime runs on our own gateway, deployments are automated, and the code is documented. What's left is the hard last mile: making the live ride experience feel as smooth and reliable as the incumbents, finishing the apps, and getting the platform ready for real scale. We...
I’m adding a completely new piece of functionality to my existing mobile application and need an experienced mobile developer to take it from concept to release-ready code. The current app architecture is well-structured and fully documented; I’ll share the repo, API endpoints, and design mock-ups as soon as we begin. You’ll be responsible for: • Building the new screens, business logic, and any required API calls • Ensuring the feature runs smoothly on both iOS and Android with clean, maintainable code • Writing unit/functional tests and updating the build pipeline so our CI picks everything up automatically • Delivering concise setup notes and a short walkthrough video so my in-house QA can verify the work quickly Acceptance criteria: 1. Feat...
I’m ready to build a full-featured transportation booking app and need a developer who can take it from concept to launch on both iOS and Android. The core flow is simple: a rider opens the app, schedules or books a ride in real time, watches the vehicle approach on a live map, and—when necessary—contacts the driver through an in-app phone call or text without revealing personal numbers. Key functions I have in scope: online ride booking and scheduling, GPS-based live tracking, push notifications for status updates, secure payment integration, and the direct call/text bridge mentioned above. A lightweight admin console for trip monitoring and basic analytics will also be required so I can keep an eye on fleet activity. I’m looking for a clear, detailed project...
Hi freelancers, We have a fully functional Matrimonial Application that was recently published on the Google Play Store [Play Store]. The app frontend is stable, but the backend is running on an outdated tech stack. We need an experienced developer or team to upgrade our entire system to modern standards for security, speed, and scalability. Our Current Tech Stack (Advanced Version): • Mobile Frontend: Flutter / Dart (Null-Safety compliant) • Backend Admin Panel: CodeIgniter 3.x • Server Language: PHP 7.4 • Database: MySQL 5.6 (Legacy version) What We Need From You (Scope of Work): 1. Backend Migration: Rewrite and migrate the full admin panel and REST APIs from CodeIgniter 3 to the latest Laravel (11.x or 12.x) on PHP 8.2+ [Laravel 12.x Releases]. 2. Database Upgrade &...
I want to launch an Android and iOS application that mirrors the core experience of Bubbly Live—real-time streaming, one-to-one video calls, and virtual gifting—while still carrying my own branding touches. The interface should feel instantly familiar to regular Bubbly users, yet stand apart through subtle design tweaks that we will define together (think updated colours, iconography, and motion cues rather than a full layout overhaul). Core scope • Low-latency live streaming rooms that support thousands of concurrent viewers. • One-to-one video calling initiated either from a stream or directly from a user profile. • Gift-sending system with animated effects and a creator revenue share logic. • In-app wallet and consumable coin balance, including p...
We are a licensed financial institution operating across West Africa and I want to purchase a complete, production-ready Flutter codebase that can become our official mobile banking application. The same code should compile cleanly for both iOS and Android without forks or feature gaps. Core user flow • Sign up and sign in strictly through phone number + one-time-password (no email/password fallback). • Fully authenticated users must be able to: – view real-time account balance, – deposit funds, – withdraw funds, – transfer funds to another in-app user, and – convert balances between multiple currencies in-app. Required currency coverage (for conversion engine) • USD • EUR • XOF (CFA Franc) • UGX ...

I need a small, no-frills mobile app that lets the user enter two numbers, tap a button, and instantly see their sum. The project must ship for both Android and iOS from the same code-base, so Flutter or React Native make sense, but I am open to any toolkit that meets Apple App Store and Google Play requirements. Core logic is straightforward—add the two numbers—but I also want the result stored locally in a running history so users can review past calculations anytime they reopen the app. No sharing features or custom UI themes are required beyond a clean, modern layout with responsive text fields and a clear results area. I’ll consider the job complete when I receive: • Build-ready Android (APK/AAB) and iOS (IPA) packages • Source code with clear comments ...

I’m moving the APAC VLA (Visual Language Action) initiative from concept to reality and need a creative partner to craft engaging interactive media specifically for mobile apps. The core goal is to produce original visual content that feels dynamic and intuitive on a small screen, transforming abstract ideas into touch-ready experiences that resonate across Asia-Pacific audiences. Here’s what I have in mind: animations, micro-interactions, and seamless transitions that load quickly, look crisp on high-resolution displays, and work smoothly in both iOS and Android environments. You’re free to choose the production stack—whether that’s Unity, React Native, Flutter, Lottie files, or another toolset—so long as the final assets integrate cleanly with our exi...
I have a 6-7-screen mobile app that combines AI chat, smart agents and image generation, plus a daily free-coins feature. The core flow, navigation layout, button styles and typography work well, so I want to keep those. What I need is a fresh, modern look in a light colour scheme that makes the whole experience feel clean, intuitive and cohesive. You will focus solely on the UI layer—no code changes, just the visual redesign. I’ll supply the current mock-ups (Figma) and a quick walkthrough video so you can understand the user journey. From you, I’m expecting updated Figma frames for every screen, component states, and a brief style guide that lets my developer swap the assets in without rewriting the existing layout logic. If you’ve delivered modern, light-themed...

I need a complete, production-ready mobile application (iOS and Android) that lets users hold Rupiah-based crypto assets, send and receive them seamlessly, and review a clear, immutable transaction history. From the same code-base I also want a built-in swap engine so users can exchange their Rupiah token for other coins, plus a lightweight point-of-sale module that merchants can run on a tablet or phone to accept the same assets at checkout. Security comes first, so please apply best-practice key management (encrypted local keystore, biometric unlock, optional hardware-wallet pairing) and audited open-source libraries wherever they fit. A crisp Flutter or React Native front-end is fine as long as the results feel native; Kotlin/Swift twins are welcome if you prefer. Because the supporte...
I’m building a mobile learning experience that runs smoothly on both iOS and Android. The core of the product is a mock-test module paired with real-time streaming classes so students can practise, review, then join a live session immediately if they need deeper guidance. Mock-Test Module • Each test must start its own countdown timer and auto-submit when time expires. • Answers are checked the moment a student taps “submit”, with clear right/wrong indicators and brief explanations. • When a test ends, the app should generate a detailed score report covering overall marks, topic-wise performance, accuracy, and time taken per question. Live Class Module Real-time streaming is essential: learners join a session, interact through chat or quick polls,...
I need a cross-platform mobile app (native or Flutter/React Native is fine) that becomes the digital “clubhouse” for my shooting association, available on both iOS and Android. Core idea Members, coaches, and administrators should each log in and see a tailored dashboard. For members, the focus is on personal metrics and statistics—think scores, weapon categories, training hours, accuracy charts, and similar data visualisations. Coaches must be able to review those same stats in aggregate, assign training programs, publish events, and record notes.

Here’s what I’m picturing: • Web portal: modern UI, fully responsive, SEO-friendly, deployed to a scalable cloud host. • Mobile apps: native Swift/Kotlin or a polished cross-platform stack such as Flutter or React Native—whichever you’re most confident will deliver native-level performance. • Backend: secure authentication (JWT or OAuth 2.0), REST or GraphQL API...
12NM – Build a New Professional Mobile App + Web Platform We are looking for an experienced developer or small development team to build a new professional version of our 12NM platform for iOS, Android and Web. 12NM already exists as a working PWA prototype. It was created quickly and in a simplified way because the first version was developed by someone without professional programming experience. Because of this, the current version has many limitations, bugs, performance problems and things that are difficult or impossible to change. We do NOT want to simply convert the current PWA into a mobile application. We want to build a new and much better 12NM platform based on the existing concept, features and experience we already have. The current PWA is only a reference/prototype. It ...
